What are the hazards of having smaller front tires and larger rear tires?
1 Answers
Tires with smaller front and larger rear sizes can cause the front wheels to have an increased turning amplitude during steering, which may easily lead to loss of vehicle control. Below is an introduction about wheels: The function of front wheel toe-in: Front wheel toe-in ensures the stability of the vehicle's direction during driving and allows the direction to automatically return after steering, while also reducing tire wear. It has the effect of turning the wheels inward, which can offset the adverse effects caused by front wheel camber, enabling the wheels to roll straight without lateral skidding, thereby reducing tire wear. The deformation of the suspension system's hinge points also causes the front wheels to have a tendency to turn outward, which must be compensated for by front wheel toe-in. The rotational planes of a car's two front wheels are not completely parallel but have some angle, a phenomenon known as front wheel toe-in. Front wheel toe-in is mostly between 0 to 12mm. Modern cars tend to have reduced or even negative front wheel camber angles, and the front wheel toe-in should also be correspondingly reduced or even negative. The functions of wheels: Support the entire weight of the vehicle and bear the vehicle's load; transmit the torque of traction and braking to ensure the adhesion between the wheels and the road surface; mitigate and absorb the vibrations and impacts during driving, preventing severe vibrations and premature damage to vehicle components, adapting to the high-speed performance of the vehicle and reducing driving noise, ensuring driving safety, handling stability, comfort, and energy efficiency.
